A Chinese research team has demonstrated a 1Gbps laser downlink from a satellite 36,000 kilometers above Earth using just a 2-watt laser, outperforming Starlink's low Earth orbit satellites. The key was embracing atmospheric distortion rather than fighting it, rebuilding the signal from scattered fragments using 357 micro-mirrors and a multi-plane light converter. This challenges assumptions that more power equals better performance and suggests optical satellite communications can be more resilient and adaptable than previously thought.

Why it matters

This breakthrough in long-distance optical communication could revolutionize backbone networks, enabling high-capacity data relays in remote areas or disaster zones where traditional infrastructure is down. It also suggests optical satellite communications may be more powerful and versatile than low Earth orbit constellations, potentially paving the way for interstellar communication.

The details

The Chinese team demonstrated 1Gbps speeds from a satellite 36,000 kilometers above Earth using just a 2-watt laser. Traditionally, atmospheric distortion has been seen as an obstacle, but the team embraced it, using a ground receiver with 357 micro-mirrors and a multi-plane light converter to rebuild the signal from its scattered fragments. This increased the usable signal from 72% to 91.1%, dramatically improving reliability. The low power requirement also challenges assumptions that more power equals better performance.

  • The demonstration took place recently above Yunnan Province in China.
